MOA-23 (Fatty alcohol polyoxyethylene (23) ether, CAS: 68439-50-9) is a high-degree polymerized nonionic surfactant, appearing as a white waxy solid, with an HLB value of about 16–17. It exhibits excellent emulsifying, dispersing, wetting, and acid/alkali resistance. Its high cloud point allows it to adapt to high-temperature operating environments, and it demonstrates good compatibility with anionic, cationic, and amphoteric surfactants, making it widely used in many industrial fields.
This product is known for its high active matter content and batch-to-batch quality stability, enabling efficient emulsification and dispersion with minimal dosage. At the same time, MOA-23 has good biodegradability, aligning with current environmental trends, making it an ideal choice for industrial formulations that balance performance and environmental friendliness.
1. Textile Printing and Dyeing Industry: Used as a leveling agent and dispersant, effectively preventing dye aggregation and ensuring uniform fabric dyeing, especially suitable for high-temperature and high-pressure dyeing processes. The product aliases "Peregal O-23" and "Leveling Agent O-23" originate from this application.
2. Industrial Cleaning Industry: As a core component of hard surface cleaners and metal degreasers, it has strong emulsifying and degreasing capabilities, quickly stripping heavy oil stains and carbon deposits from metal surfaces, making it an ideal choice for heavy-duty industrial cleaning formulations.
3. Household Washing Industry: Used as a nonionic surfactant in laundry detergents and laundry powders, providing excellent emulsification, detergency, and anti-redeposition properties, while also offering foam control to enhance overall washing performance.
4. Cosmetics and Personal Care Industry: With a high HLB value (approximately 16–17), it is an ideal emulsifier for O/W (oil-in-water) emulsion systems, and can also be used for solubilizing hydrophobic components such as fragrances and essential oils, improving product texture and user experience.
5. Leather Processing Industry: As a component of efficient degreasing agents, it effectively removes natural fats from raw hides and provides good wetting and penetration capabilities during subsequent wet processing.
6. Papermaking Industry: In the deinking process of waste paper recycling, it serves as an effective deinking agent, efficiently separating and removing ink particles, improving pulp brightness and deinking efficiency.
7. Emulsion Polymerization Industry: Provides stable emulsification for emulsion polymerization systems such as acrylates and styrene-acrylics, producing polymer emulsions with uniform particle size and good storage stability.
